Abstract

Linear correlations are found between concentration of water in a solution of ethanol and effect
of swelling of polyacrylamide granules with 3% crosslinking, polyvinyl spirit a with 20% crosslinking
and the natural logarithm of relative volume of a bulking up granule. It is established that the
microimpurity which are present at spirit, do not influence volume effects of swelling. It is shown that the
found dependences can be used in an alternative way of definition of the maintenance of water in a
solution of ethanol in a range of 4-100 mass. %.
